Hello Giles,
i was reading conver in the forum regarding GSLB..is GSLB only failover for servers? few days back we raised a question to our isp to provide us BGP failover. they too mentioned abt gslb but i wasnt convinced. wht we want
ISP 1---site 1---css1-- Pri web servers
ISP 2---site 2---css2---sec web servers
as i understand when the requests comes to css1 (assuming gslb is configured between css1 and css2) it acts like dns and send the traffic to pri web servers...so theres some comunication between css1 and pri webserves ..some kind of keepalive..for request to come in to css1 , my link with isp1 or the path to isp1 on the internet shd be available...my question is , wht if the link to isp 1 fails, or isp 1 is not available over the internet, how will the requests get routed via isp2 to css 2 and then sec web servers..wht kind of intelligence will make it happen..BGP is implemented to do failover ISP's, will GLSB help in doing the same
